FAQ’s on Aldehydes and Ketones in JEE

Joint Entrance Examination (JEE) is a common entrance exam conducted for admissions to various prestigious engineering colleges in India. Chemistry is one of the most scoring subjects to enhance one’s rank in JEE. According to the JEE syllabus, chemistry is subdivided into inorganic chemistry, organic chemistry and physical chemistry. Organic chemistry is one of the most important among the three as it generally has a higher weightage in JEE question paper. In organic chemistry, aldehydes and ketones form an important topic to cover. Some FAQ’s related to aldehydes and ketones are underlined below:

Question: What are some of the important topics in aldehydes and ketones for JEE?

Answer: According to JEE syllabus, this topic contains the reactions involving preparation of aldehydes and ketones and their chemical and physical properties.All the reactions of aldehydes and ketones are of utmost importance. Try to understand all the reactions with the involved mechanisms as every year 4-5 questions are asked related to these reactions.

Aldehyde Ketone

Question: What type of questions are asked in JEE from aldehydes and ketones?

Answer: In JEE, questions asked on aldehydes and ketones require deep understanding of concepts. Generally, questions are asked to predict major or minor products of a reaction or a series of reactions involving aldehydes and ketones.

Illustration: Aldolcondensation is not possible for which of the following compounds?

  1. CD3CHO
  2. CH3CHO
  4. PhCHO

Answer: PhCHO, as it does not contains any alpha hydrogen.

Questions: Which reference books can one follow for aldehydes and ketones?

 Answer: While covering aldehydes and ketones for JEE, one must go through the NCERT class 12th chemistry textbook part-2. A brisk walk through this chapter from NCERT not only gives you a sound idea of the various topics you need to cover but also develops the fundamentals regarding the chapter. Apart from this, you can follow a reference book to understand mechanisms of the reactions not given in the NCERT textbook. Some authentic books for understanding the mechanism of organic reactions includes books from authors like Solomons&Fryhle, Morrison &Boyd. Once you have developed concepts on this topic, you can practice questions from the books of authors like M. S.Chauhan, etc.
